Why does Pre-Check have to be so complex? I'll start off with, it's a great idea. I'm glad they're instituting it, and look forward to utilizing it, seeing it expand...

That being said, why can't anyone enrolled enjoy the benefits always? I will be enrolled, as I'm GE and was targeted as a CO elite. Why does it only work for AA at some airports, and DL at other airports? As a TT, I should have a number to put into my online profile when booking travel. It shouldn't matter what airline I'm flying or what airport I'm using. As long as Pre-Check is set up at that airport, anyone enrolled should be able to benefit.

Perhaps, they shouldn't bother encoding the BP. Otherwise, if I'm flying a foreign carrier, how will I ever benefit?

The system is a great idea. But with tweaks like this, the TSA could really go a long way to restoring some faith in travelers everywhere.
